in Python
%%python3
from pathlib import Path
D = Path('/home/abanoub/Work')
files = [(i, i.stat().st_mtime) for i in D.iterdir()
if i.is_file()]
result = sorted(files, key = lambda w: w[1])[::-1][3:]
for file, day in result:
file.unlink()
in Bash script. find command shows randomly, so we use ls -t.
%%bash
files = ($(ls -lt ~/Work))
len = ${#files[@]}
for ((i=3; i < $len; i++))
do
rm -f ~/Work/${files[$i]}
done
in Perl
perl -e'opendir$h,"/tmp";@f=sort{-M$a<=>-M$b}grep{-f}readdir$h;unlink@f[3..$#f]'
